DI$TBLEBUTER 'EQR ELEGTRIUAL KG?) To all whom it may concern:

Be it known that I, ANTQN Dionne, a sol ject'of the Emperor of Germany, residing at and Whose post-oflice address is'Lerchenstrssse 77, Stuttgart, Germs; y, have invented certain new and. useful improvements in Distributors for Fri ignition Systems; and Ii (lo i'lC].Qi1) i. are ti'xcfoliowing to he a full, clear, snC description of the invention, such 11" enshie others skilled in the art to i t sppcrteins to make and use the some. I

The present invention relates to distrihu ters for electrical ignition systems or internsi combustion engines, anti particularly to one wherein the contact orush'or brushes connected. to the ignition system and also the contact segment or segments connected to the spark plug or plugs of the engine are normally stationary, while rotory contact member is arranged. to connect the contactbrush or brushes with the contact 5 rent or segments in the desired ortier to the clesired order of ignition of the comb' tible mixtures. In its preferred form for a multiple cylinder engine, there is it normally stationary contact segment for each engine cylinder o'reach spark plug, vwhereas the t-ary contactmember is provider]. with a like number of Contact sec-merits arranged to engage the contact brush or brushes, and also 'proyidedwith oicontect brush electrically.

connected "to gillthe Contact segments of the rotary member end adapted to engage the normally tationery contact segments in order to thereby electrically connect the normaily-stationsry contact brush or brushes with the normally-etationsry contact segments in turn.

As an example of its application, I here shown my distributor embodied in electrical ignition system for starting and running multiplccylinder internal combustion engines, wherein there is one normeii pstw tio'nsry contact brush electrically connected to a service magneto driven from the engine together with the rotary part the distributcr for ignition during running, and.

also. a second normally-stationery Contact brush singularly displaced from the first and electrically connected to a starting msgneto disconnected from theengine so as to be driven independently thereof for start.- mg the engine from rest by ignition. An

tion, in such manner that the source of sup-H ply for starting ignition is connected to the" spark plugs intern in the compression po riotis offthe corresponding pistons, while the source of supply for running ignition is con nected to the spark plugs in turn in the Working periods of the corresponding pistons. y

In the accompanying diagrammatic drawings, illustrating the application of my distrihuter to an electrical ignition system having an engine-driven service magneto for ,lgnltion durmg running and a starting Ina-g neto riisconnected from the engine for starting the engine from rest by lgmtion, as an example, Figure 1 shows the distributor in the position inwhich the service magnet/o is connected to one of the spark plugs in a cylinder of a four cylinder engine, as an example; anti Fig". 2 shows-the position of the {ilShllbllit-l' in much the startlng magneto 15 connected to the same spark plug.

in the drawings, A is av starting magneto disconnected "from the engine so as to be driven independently thereof in any suit able Way. this terminal of the primary Winding is connected through the mechanical interrupter a to the ground, ant the other tern'iinal is connected directly to the I ground, as shown, this terminal of the seoontizrry "Windingis grounded While the other terminal is connected through the slip ring, a to the normally-stationary contact brush m. I

ihe service magneto B is driven from the engine for the purpose of supplying ignition currcntsduring running. The primary Winding and the mechanical interruptcr Z: are connected .as in magneto A, While the seconsry winding is' connected through the slip ring 7) to the normallyststiornny contact brush Z; The distributer .is prov ded with a normally-stationary d1s' trihuter member having the insulated contact segments 1, 2, 3 and 4:, Which are electrically cohnccted. to the insulated electrodes tar) eoutaet member h ot the llistrihuter is '(ler requiring: the next spark to (ll-iron by the engine and eoiuprises the eontaet segments 3,. a 5 and a, eleetrieally ()l|ll((it(l togethe unit to the eontaet brush a. as shown. The eontaet. segments .3 s 8;, aml .51, are ar 'angeil to engage the eon'taet brushes m auil Z in turn, while the c'ontaet brush x is arranged to sueeessively engage the ilistributer se 'ments 1 2 3 tllltl 4. In

Fig. 1, the brush Z is engaged with the contart seniiieiit 8; and the brush 8 engaged with the distributor segment 1, so that at this time the ignition current produced by the serriee magneto B is eoiulueted to the spark plup; K, to IllOtlllCQ a spark thereat and thereby ignite the eomhustible gas in the cylinder Q. in Fig. 2 the eontaet brush a is still engaged with the eontaet segment 1, but the eontaet seguwnt 5 is non engaged with the brush m, instead of 8;, and Z being in engagement, so that now the starting magneto 'is eonneetml to the spark plug 1 whereas before the serriee magneto l3 was eonneeteil thereto. The distributor eontaets 1, 2,3 and -lare given sueh a peripheral e3:- tent that thecontaet brush s eontinually eneagles each of them (luring the whole of the two periods in which the brush Z engages one of the rotary eontart segments and in \i'hieh the brush 1/1. engages the rotary eontaei segment; Whieh is in atlranee of the other one in the rlireetion of rotation of the (listributer. This arrangement proriiles tor the proper eoiuuietion to the spark plugs: in respective of the advanced or ietarileil adjustment of the ignition period of the system.

l he distributor parts are so arranged relatively to the stroke ol the engine that at the position shoi n in. Fig. l. the pisto'n of the \'lintler (,7, is in its working: stroke, while the serriee magneto ii is arranged to pro (lure its ignition eurrent at this {HFI'lOfl. Thus the system is elleelire to bring ahout ignition ot the oonibustiblr mixturea in the eyliuileri-i in turn in the usual way (luring running ot the engine. the starting; magneto A not being tlllYtll then llllti tluJ-rei'ore not iuterl'erine in any Way with the normal op eration.

its has heen pointed out in the iiateulreterreil to. internal eonihumion engines. on automobiles or in other applications. alwaji's texul to stop at sueh posit'i m that the eylinstart the engine in the proper ilireetion oi rotation is in its eouu u'ession stroke. ileeorilia the ilistributer is arranged so that one oi the contort segments an, #1, A1,, a then in enn'a uuueut with the eoulaet hrush iii .Wlllil" the eoulai-l hrur-h a is in iuent wit" that one ot the eoniart segmenr l to the spin-l; plug in the ens a in eylintler requiring ignition. Therefore, if the starting magneto A be driven when engine is at rest the ignition currents pro (lll((tl thereby will he conducted to the proper spark plug and produce a spark thereat to start. the engine in the proper reetion. provided, of course, that minibus-- tihie. mixture has remained in the cylii'iclor or pumped therein before or at the time oi? operating the starting magneto. As soon then as the service magneto B supplies satis" l'aetory ignition sparks, the operation of tho starting magneto may be discontinued, the engine then operating in the ordinary Way as pointed out above.

It will be understood that any other snitable kind of source of ignition current may hoeinployed instead of the starting mag neto it or the service magneto B, or both, anti that the distributor herein shown he used in other ignition systems wherein there is a single source of ignition current instead of the two sources A and i3. and single contact hrush instead of the two brushes 1 and m. Furthermore the distritn uter shown may he used with an. internai combustion engine having one or-uny other number of eylinders, besides the four eyiiir (lers shown.
